Deliverable D1.5 CECs in soil including D1.6 ...

The aim of the deliverables D1.5 and D1.6 was to determine the fate of the CECs in soil and plant uptake, after long-term crop irrigation with the effluent of SERPIC technology Route A. The field test was conducted by growing carrots and potatoes in soil, irrigated with three different water qualities: municipal tap water, water from a WWTP secondary effluent and the effluent from the SERPIC technology Route A. Soil and crop samples were collected at UCLM in July 2024, and transported to a laboratory at Stellenbosch University, South Africa, where it was analysed for the presence of CEC’s. Low or undetectable levels of sulfamethoxazole, diclofenac and iopromide were detected in soil and crops irrigated with secondary effluent from both the WWTP and Route A. Venlafaxine could be detected in low concentrations in soil samples and the leaves of potatoes and carrots irrigated with both secondary WWTP and Route A effluent. Results include LC-MS analysis of soil and crops, sampled after a long-term field study involving irrigation with Route A effluent in comparison to secondary WWTP and tap water.
